.IX Header "DESCRIPTION"
dbar lets you define static 0% and 100% marks or you can define these
marks dynamically at runtime.  Static and dynamic marks can be mixed,
in this case the value specified at runtime will have a higher priority.
.PP
You can specify ranges of numbers, negative, positive or ranges with a
negative min value and positive max value.
.PP
All numbers are treated as double precision floating point, i.e. the
input is \s-1NOT\s0 limited to integers.

.IP "\fB\-l\fR" 4
.IX Item "-l"
Label to be prepended to the bar (default: "" ).
.IP "\fB\-nonl\fR" 4
.IX Item "-nonl"
no new line, don't put '\en' at the end of the bar (default: do print
\&\*(L"\en\*(R")
.IP "\fB\-max\fR" 4
.IX Item "-max"
Value to be considered 100% (default: 100).
.IP "\fB\-min\fR" 4
.IX Item "-min"
Value to be considered 0% (default: 0).
.IP "\fB\-s\fR" 4
.IX Item "-s"
Symbol represeting the percentage value in the meter (default: \*(L"=\*(R").
.IP "\fB\-w\fR" 4
.IX Item "-w"
Number of charcaters to be considered 100% in the meter (default: 25)
.SH "EXAMPLES"
.IX Header "EXAMPLES"
Static 100% mark or single value input:
.PP
.Vb 1
\&    echo 25 | dbar \-max 100 \-l text
\&
\&    Output: text  25% [======                   ]
.Ve
.PP
If your 100% mark changes dynamically or 2\-values input:
.PP
.Vb 5
\&    echo "50 150" | dbar
\&          |   |
\&          |   |_\|_ max value
\&          |
\&          |_\|_ value to display
\&
\&    Output: 33% [========                 ]
.Ve
.PP
If your value range is not between [0, maxval] or 3\-values input:
.PP
.Vb 7
\&    echo "50 \-25 150" | dbar
\&          |   |  |
\&          |   |  |_\|_ max value 100% mark
\&          |   |
\&          |   |_\|_\|_\|_\|_ min value 0% mark
\&          |
\&          |_\|_\|_\|_\|_\|_\|_\|_ value to display
\&
\&    Output: 43% [===========              ]

Multiple runs:
